Particle Model of Matter Flashcards
what are the 4 principles with the particle model of matter
all matter is made up of particles
there are forces of attraction between the particles
there are spaces in between the particles
the particles are always moving
what can we use the particle model of matter for
to understand the behavior of each of the states of matter
for each individual particles of matter they are what
the same in all 3 states
what is the arrangement of particles in a solid
packed close together in a pattern
what is the movement of particles in a solid
vibrate in a fixed position. low energy
what are the forces between the particles in a solid
held together by strong forces of attraction
what are the spaces in between the particles in solids
small spaces
high density
what is the compressibility in a solid
incompressible
what is the arrangement of particles in a liquid
packed closely in a random way
what is the movement of particles in a liquid
move faster than is solids and slide past each other, more energy
what are the forces between the particles in a liquid
forces are not as strong as solids
what are the spaces in between the particles in liquid
small but larger than solids
what is the compressibility in a liquid
incompressible
what is the arrangement of particles in a gas
no arrangement, far apart
what is the movement of particles in a gas
move around fast
high enerygy
what are the forces between the particles in a gas
very weak
what are the spaces in between the particles in a gas
large
what is the compressibility in a gas
can be
give the definition of diffusion
diffusion is the movement from an area of high concentration to a area of low concentration
give examples of diffusion
air freshener
bath bombs
what is the rate of diffusion
the speed at which particles diffuse
what are the factors that affect the rate of diffusion
the size of the particle
the speed of the particles
the temperature of the particles
the size of the spaces between the particles
